It is endlessly frustrating that companies have universally decided that they won’t let people say “no” to stuff, ever. There are no longer options to reject stupid-ass new “features”, only postponement until next time you open the app/website/program. They’ll continue pestering you for the rest of your life. I realize that my frustration may be a little over-zealous, but we deal with these interfaces dozens of times per day and this is user hostile behavior. There isn’t really an option to just use another service or program, since the entire technology landscape has been commandeered by a few major corporations, and they all enact the same shitty things as a group.
Companies like this are abusing you as a paying customer. I would use newpipe if you’re on android or if apple has any alternative to newpipe then use that otherwise use firefox with ublock.
I use piped.video for the dozen or so subscriptions I have. I don’t have an account, I once exported my subscriptions and when I erase browser history I upload that subscriptions file. All I want to see on YT is right there.
